Hi,

Photographs of texture-generated textures often have two nose errors. Re-marking feature points still cannot be resolved. So how do you solve this error?

Thanks.

This can sometimes happen, especially when photos are not taken according to the guidelines. In this case, the hair covering the left part of the face is causing problems for FaceGen, and the lighting from the side rather than the front could be a factor. Here are the guidelines:

"Outer edges of the nose flaps."

I have always had problems with these instructions.

They hint where to place the "x" position, but no "y" position hint is given.

Can someone tell me, where is optimal location for "y"?
- Tip of nose?
- Center of nostril opening?
etc...

Thanks

FaceGen is designed to accept some variation in the Y position, so just try to find the X-outermost point of the nose flap.

The issue of two nostril holes in the color map is likely not caused by placement of these points. It is likely just due to limitations of our algorithm in some situations.

Best wishes,

First, I place nose markers level with the top of the nostril. Facegen is kinda weak making noses but there is a way to get around it.
I have SI Facegen version 3.5.3 build March 2011.

I learned a nice tip that if you morph the actual photo's nose and nostrils to match SI Facegen's face texture, then paste a cutout of the photo's morphed nose onto the face texture, blur the edges of the cut out, make it translucent to match the position of the face textures nose, then get rid of the translucence, then adjust color and tint and brightness of the cut out, the nose on the character can be spectacular. Check out some characters I made for the game Elder Scrolls 4, Oblivion. using an old copy of Windows 2000 Picture It in Windows 10 to do the PhotoShoping of the photo and the face texture:

I begin by cutting out a copy of the face textures nostrils and pasting next to the photo's nose to be used as a guide before morphing the shape of the photo's nose.

Looks like your subject's face is tilted slightly downward. The lip line should be straight or slightly bowed upward (as seen in face texture) when the face is truly aimed straight ahead. No hair over eyebrows. Head is also tilted sideways which can also effect nose outcome. You can easily rotate the head to a vertical position in photo editing software. I find best result is placing markers level with top of nostrils. The lower nostrils in your face texture are Facegens programmed positioned nostrils while the upper nose are your photos.

Here is my face texture after editing. Nose has been morphed from photo and pasted onto face texture. used cloning tool to replace edges of facegen nose with surrounding skin near nose.

Notice right column has items I used to construct nose as well as brightened/color matched oval cut out for better neck/body seam match.

Looks pretty good.  I might give that a try.  Usually have to do a bunch of fancy clone stamp Photoshop work to get the nose right, but this might be faster.
